Zachary Quinto is best known as Spock in J.J. Abrams' Star Trek reboot and its sequel, Star Trek: Into Darkness. Quinto previously played Sylar on NBC's Heroes and is currently in The Glass Menagerie on Broadway.
Agent 47, the follow-up to the 2007 Hitman film starring Timothy Olyphant, was originally set to star Fast & Furious star Paul Walker before the actor passed away in a car crash last November. Earlier this month, news that Homeland's Rupert Friend was set to replace Walker proved the project would carry on despite Walker's death.
The film will be directed by Aleksander Bach, based on a script from Skip Woods and Michael Finch.
